Paris Weather in May
Planning a trip to Paris in May? Here's what the weather is really like during one of the best (and busiest) months of the year to visit.
May in Paris is genuinely close to perfect. Highs settle into the mid-60s to low 70s°F, lows climb into the upper 40s and mid-50s, daylight stretches long into the evening, and the city's terraces and parks come fully alive. Rain averages 9–10 days, but the bigger weather story this month is the thunderstorm potential — the Azores High expands, cold troughs sweep in from the north, and the collision can fire off convective storms with lightning, gusty wind, and occasional hail.
There's also a quietly fascinating local weather legend worth knowing: les Saints de Glace (the Ice Saints), a brief late-May cold snap that French farmers have tracked for centuries. Meteorologist Ian Schwartz breaks down what to expect.

What are les Saints de Glace?
Les Saints de Glace (the Ice Saints) is a centuries-old French weather tradition tied to three saints' feast days in mid-May (May 11–13). Farmers historically waited until after these days to plant frost-sensitive crops, because a final cold snap from the north often shows up around then. It's folklore, but it tracks with real meteorology: a late-spring trough can still drop temperatures briefly. If you're road-tripping the countryside, bring a jacket. In central Paris, it's rarely a big issue.
Is May a good time to visit Paris?
Many would say it's the best. Temperatures are comfortable, daylight is long, terraces and parks are fully alive, and the city is at its photogenic best. The main considerations: it's peak travel season, so book early, and be ready for occasional spring thunderstorms. Don't pack rigid outdoor itineraries.
